If you will pardon my not being familar with the speaker, I'd presume these posts are for "biwiring" and not "biamping". I certainly might be wrong. I'm sure the fine chaps at the Klipsch forum might know more details.
That said, you can certainly biamp the speaker. The 30 watt difference between the amp is irrelevant when you are biamping with an active crossover in the chain.
(so you know, I biamp)
I once had an 8 watt 300B SET amp wired to my tweeter and a 500 watt Crown K2 amp wired to my woofers. Worked like a charm. It worked like a charm as long as I stayed within the output range of the 300B. Once I went past that, I could hear the tube amp running out of gas and the distortion took over.
You can also adjust for different input sensativies inside an active crossover.
I guess....what I'm trying to say is if you are thinking about simply running one amp to one post and the other amp to the other post, I would personally pass on that arraingment. If instead, you are thinking about adding an active crossover PRIOR to the amps so that each amp only covers a part of the spectrum, then you might continue forward and find out what the next road block is (how the passive is setup in the speaker)
You don't want to set up an actively crossed signal and then feed essentially, 1/2 of that signal into the unaltered passive. If you add an active crossover, you will need to do SOMETHING (I'm not exactly sure what) to the passive.
I'm fearing you are referring to "biamping" where you remove the strap on the speaker, run an additional line to the input cup from your second amp and are done? If accurate, I'd personally pass.
My thoughts are, if you're going to biamp, then do it right.
